Communication method and device

Abstract

Embodiments of the present application provide a communication method and device, the method comprising: a first network element receives a first request from a terminal device; wherein, the first request includes an identifier of the terminal device; the first network element receives a first request according to The first request sends a second request to a second network element; wherein, the second request includes an identifier of the terminal device; the first network element receives a first shared key from the second network element; Wherein, the first shared key is determined by the second network element according to the second shared key, and the second shared key is determined by the second network element according to the identifier of the terminal device; The first shared key is used for security protection in the first network, and the second shared key is used for security protection in the second network. In the embodiment of the present application, the first authentication architecture and the second authentication architecture can realize intercommunication, which improves communication flexibility.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] With the development of communication technologies, the reliability of network services is increasingly required in the communication process. Therefore, operators and users usually need to use authentication mechanisms to ensure the reliability of network services. Specifically, the authentication mechanism may be that two-way authentication is implemented between a user terminal (User Equipment, UE) and an application server through a key or the like. [0003] At present, the authentication methods between the UE and the application server are: the authentication method based on the Generic Bootstrapping Architecture (GBA), which can be applied to the third-generation mobile communication (3fifth-generation, 3G) and the fourth-generation mobile communication (4fifth-generation, 4G); with the d...

Problems solved by technology

[0004] However, the current GBA-based authentication system and the AKMA-based authentication system are independent of each other and cannot communicate with each other, resulting in poor authentication flexibility.
